Figs. 16 and 0f the cams on the driving-shaft strikes and 17 are side views, partly broken away, of the adjoining ends of the raceway and chute, showing the Vmain part of the escapement in section; and Figs. 18 and 19 are respectively a horizontal section and a plan of the same parts, the escapement device being shown in section in the one case and in plan in the other.

The main frame of the machine comprises a base-plate A, open-work sides B, and table C. A foot D, carrying a vertical sleeve D to receive the horn E, and being hollow to allow a lever D2 to be pivoted therein, so that one of its arms will engage in a notch c in the side of the horn near its lower end and the other arm will project out from it, is bolted to the base-plate A, toward the front of the machine.

The driving-shaft Fof the machine is horizontal and has its bearings in the standard F', bolted on top of the table near the rear and in the vertical head G, (where the driver is located,) carried by a neck portion G', cast on top of the table and projecting out beyond its front edge.

A tight and a loose band-pulley, respectively lettered H and J, and three cams K, L, and M are mounted on the driving-shaft F in succession between the standard F' and the head G, and a crank-disk N is set on the shafts rear end.

rlhe clutch mechanism for throwing the power on and off is not shown, as it can be of any ordinary kind. Y

1n vertical lines with the cams K and L, which have the respective "rises 7c and Zon their peripheries, are respectively arranged rods K' and L', the former extending from a bridge-piece K2 (shown in Fig. 3) down to the lever D2, to which it is pivoted, passing freely through such bridge-piece and the table, and the latter-that is, the rod L-h aving its upper end bent horizontally to lie on the cam L, while its main length extends down through the table and through a ledge L2 on the end of a hanger L2,bolted to the under side of the table. Two clamp-plates K4K5, (shown in plan in Fig. 10,) each perforated at one end to fit loosely the rod K', are located on same, so as to be pressed by a coiled expansion-sprin g K6, encircling such rod between them respectively upward and downwardagainst the table and the ledge L2, and the outer ends of each (the plates) are in the one case K4 perforated to receive a pin projection K7 at the lower end of a bar K8, (shown in Fig. 13,) passing freely through the table, neck portion G', and bridge K2 in vertical line with cam K and adapted to be depressed by same, and in the other case K5 the end is forked to loosely iit notches L4 on the rod L' and adapted to be raised by same. Another coiled expansionspring K9 encircles the rod K' between the bottom of the ledge L2 and pins lc, located near the lower end of the rod, and a third coiled expansion-spring 7c' is arranged in a recessed boss A', cast on the base-plateA at a point beneath the end of lever D2, sothai; it can bear upward against same. Theffu'nctions of these rods, springs, and clamps will be fully set forth in a description of the operation of the machine to be given farther on.

The relative location of the horn, driver, and work-feeding mechanism is seen in Figs. 5, 6, 7, 11, 12, and 13, the driver O, a comparatively thin strip of-steel oblong in crosssection, being secured, as shown particularly in Figs. 12 and 13, edgeward to a dovetailed cross-head O', working vertically in the face of the head G, which is dovetail-grooved to `receive it, by a clamp O2 and screw O2, its (the drivers) axis being in line with that of the horn, while the work-feeding mechanism proper, consisting of a serrated Wheel P, ratchet-wheel P', and lever P2, carrying a spring-pawl p, is mounted on a stud PS, beneath-the head G, as shown in Figs. 5, 6, and 7, a second pawl p (shown in Fig. 6) being carried by the head to engage the ratchet P' and avoid back motion. The cross-head O' receives a vertical reciprocal movement from a spring-plun ger O4 above it and a roller O2 below it, carried on the front end of the vdriving-shaft F, which passes through the head G as far as to be flush with the back of the dovetail groove for such cross-head, as shown in Fig. 12. The spring-plunger O4 is held in place by two rod-supports O5 O5, projecting up from the back of the head G and carrying a crosspiece O6, through which the plunger-rod passes, suitable washers O7 being provided to prevent jarring. The cross-head O' is cut away at its lower left-hand corner, as shown at O2, so that as soon as the roller O9 passes out of the vertical axis of the driver this latter can be driven down by the plunger O4. This arrangement for raising the plunger secures a steadier movement of same, as the bearing-point of the roller O9 comes directly upon the cross-head itself, whereas when a cam is used a roller projection from th'e face of the cross-head is required for such cam to work on.

The lever P2 of the work-feeding mechan- IDA.`

IOS

ism is connected by a coiled retractile spring i P2 with the table, as shown in Fig. 7, and a lever PAl is pivoted at p to a projection P5 on a neck portion G', so that its upper arm, carrying a roller P6 at its end, will be held in contact with the face of cam M, which has a rise M' on it adapted to act on the lever to throw its lower arm outward and thus operate the lever P2. An adjusting-screw P7, whereby the feed can be lengthened or shortened, is carried by the lower arm of the lever P4 and adapted to make contact with a stop P9 on the projection P5. i

Figs. 5, 7, and 11 show clearly the chute portion Q, leading from the raceway portion of the slng-guideway to the driver. It is formed, preferably, of a separate block of vmetal with a widened foot portion Secured to the face of the head G and having three grooves milled in its rear or inner face', which are transformed into channels Q' Q2 Q2 by the face of the head G for the lower portion andv -maining upper portibn. v about five thirty-seconds of an inch in lateral by a separate backing plate Q4-for the re- These channels are depth and one-sixteenth of an inch in width, the driver O, which has one edge in contact with the face of head G, being of such section as to iind easy movement in one Q of them, which is made vertical for it to work in. The main portion of the chute is at about an angle of twenty degrees off the vertical and c'ontains the channel Q2, the remaining channel Q2 being between t-his and the vertical one Q, andboth'converging to a point in the height of this last which would be slightly higher than that of the longest size of slug used-say one-half an inch from the bottom ofthe chute.

Pivoted at r on the face of the head G is a lever R, to one arm of which is pivotally secured the end of a iiexible steel strip R', which I term the placer, its opposite end being located in the channel Q2, and as the lever R is rocked by means of two pins on the face of the reciprocating cross-head O', between which the other armof the lever is located, such free end of the placer enters and is withdrawn from the channel Q3, down which the slugs fall. p

In a groove Q5, at right angles to and in the same axis as the groove Q and near the bottom or nose of the chute, is arranged what AI term a holden this consisting of a short strip of steel Q6 with beveled point forced into the channel Q by a flat spring Q2,Which is attached to the side of the chute and carries such steel strip Q6.

The expansible raceway portion of the slug, guideway (shown in longitudinal vertical section in Fig. 9 and in end 4view in Fig. 15) is composed, essentially, of a trough-like body S, having sides and bottom and a top formed of two adjustable strips S S2, having transverse slots s s, (shown in Fig. 6,).through which setfscrews S3 pass `to the sides. The top edges of the sides are beveled so as to incline the cover-strips S S2 upward laterally toward the center of the raceway, and by beveling their inner edges a proper channel S4 (which leads into the channel Q3 in the chute) is formed for the bodies of the slugs to passdown, while the exterior surfaces on which their heads bear are reduced to mere knife edges or lines, thus lessening friction to a considerable extent. This raceway is inclined longitudinally at about an angle of thirty degrees and supported centrally by a strip S5 of metal, preferably of a slightly flexible nature, bolted at its lower end to one end of the bridge K2, so as to be in linewith the cam-K, for purposes to be hereinafter mentioned, and hav ing its free end screwed to the raceway, another point of support being the chute Q, to the side of which an extension Si from one of the sides of the raceway is screwed.

. Thenpper end of the raceway enters the slug-supplyy pot constructed and arranged as shown in Fig. 4, and now to be described. A

vertical supportT is bolted to the table in rear of the crank-disk N, and serves tov carry an oblong pot or receptacle T', open at the top and having the lower portions of its sides and part of its bottom inclined in toward a rectangular opening or space T2 in such bot-l tom situated to the right of the Whole, so as to be clear of the raceway, which is located over the left-hand portion thereof. This space T2 is normally blocked by the head T3 of a hollow rectangular plunger T4, adapted to be worked in guide-stripsT5,extending down from thepotby meansofaconnecting-rodTi,pivoted to thelowerend of the plungerand to the crankdisk N on the driving-shaft, and this head T3 has a pivoting lip or extension t on its lefthandside, through which it is hinged to the exterior of the left hand, or that side ofthe plunger nearestthe raceway. The plunger T4 is made hollow to allow of the insertion of a coiled retractile spring t therein, one end of 'which is connected with a hook yat the bottom and the other to an eye on the inside of the head T3 thereof. An inclined guide-plate T5 has its bottom edge running along the raceway parallel with and close to the channel S4 therein and its top edge in the line of vertical movement of the lip or extension t on the hinged head T3 of the plunger, so that such lip will come in contact with the plate and be tilted, as will be more fully explained in the operation of the machine. A vertical threesided guard T7 partitions off the space occupied `by the lipor extension t in traveling up and down in the pot, so as to avoid any possibility of slugs interfering.

At the foot of the raceway, as shown in Figs. 15, 16, 17, 18, and 19, is arranged whatl term the escapement device, this consisting of a steel springU bent so that one end can be secured to the extension S5 of the race- Way. Its other free end projects across the line of the travel of the heads of the slugs in the raceway, and a shoulder or bearing-point U be provided for the end of the reciprocating linger U2 to come against and move the free end out of the way of the descending slugs. This finger U2 is adjustably secured by a set-screw u in the head of a vertical lever U2, pivoted at u2 to therear side of the chute Q, as shown in Figs. 6, 8, and 11, and carrying also another finger U4 beneath the one U2 adapted to work through an opening in the raceway afforded by cutting away a portion of the end of the cover-strip S2, the cover-strip S being also recessed to a certain extent to accommodate its movement. This second finger U4 is beveled at the end and pointed, as shown in Fig. 18, so that it can be inserted between the bodies of the slugs and while moving one ofA them forward serve at the same time to hold the rest back, it always acting in concert with the spring U, which is moved out ot' the way of the slug to be fed j ust after the point of the finge-r U4 comes in, front of the remaining body ofthe slugs.

lThe lever Us is rocked by means of a linger U3, extending from a lever U, pivoted at a6 to the back of the head G and bent so that one arm will extend frontward and its end have a position directly over the upper end of the chute Q and the other arm extend downward and its end rest -on the periphery of the cam M, in which a fall ordepression mis made, into which such end drops.

If desired, the slug-guideway might consist of the raceway portion alone, which could extend from the supply-pot to a point beneath the driver, and the placer and holder be entirely omitted.

)Vith the exception of mentioning that a foot-lever W (shown in Figs. 1 and l0) is pivoted to one side of the foot D of the horn-support to be used for lowering the horn when the work is put on and removed, all the parts necessary to the working of the machine have been described, and I will now describe in detail the several safeguards hereinbefore alluded to, which are, irst, a removable cover X, consisting of a thin strip of metal bent to the cross-section shown in Fig. 6, so as to extend over the heads of the slugs, but not touch them, transversely slotted and secured in place on top of the cover-strip S by the sety screws S3; secondly, an agitating-rod, (shown in Fig. 9,) consisting of a rectangular rod X extending the full length of the raceway beneath the slugs and carried by a block X3, passing through an opening in the bottom of the raceway and pivoted on the end of an arm X3, extending from the lever U3; thirdly, an adjustable projection, (shown in Fig. 3,) which is a set-screw X4, located in the central support S3 of the raceway and adapted to be knocked by the rise 7c on cam K and so shake the raceway; fourthly, an adjustable spring retainer, (shown in Figs. 5, 1l, 14, 18, and 19,) consisting of a strip of steel X4, slightly bent into bow form and secured to the side of the chute Q at one end, so that its other end will spring inward at the mouth of the channel Q3 as far as to be in line with the channeledge of the cover-strip S3of the raceway, thus maintaining the same Width of channel "throughout, an adjusting-screw X3, threaded Y through the spring and bearing against the chute, rendering it possible to adjust same to correspond with any adjustment of the coverstrip S2. This spring or retainer has an ear X3 projecting from it, against which a pin X7, termed an opener and projecting down from beneath the end of the lever U3, in which it is held by set-screw X3, presses to throw it (the spring) outward and allow the slug resting on it to drop; lastly, a knocker, (shown in Figs. l, 2, 5, and 8,) which consists of an adj ustable linger Y, slotted and secured in place vertically on the end of the lever U3, directly over the mouth of the channel Q3 in the chute by a set-screw Y. The lever U6 receives also an opposite movement to that caused by the fall or depression fm, in the periphery of cam M vfrom a rise m. immediately following such depression, this extra movement being to operate the agitating-rod, opener, and knocker just mentioned.

To aiord access to the interior of the nose of the chute Q, I make a lower front section q of same removable, one of the screws for securing the chute in place serving-to hold such removable section in place also.

The operation of the machine is as follows: I may here remark that the horn is normally in what I term a state ot' equilibrium-1. e., the force of the spring lo beneath the lever D2 serves to make up the difference between the force of the spring K9 and the Weight of the horn, the pressure of which latter is less than the spring K3, this being necessary to allow the automatic adjustment of the horn, as will fully appear. The supply-pot T being filled with slugs and the boot being placed on the horn, (which is temporarily lowered, by pressing on the foot-lever V,) with the heel in position under the driverO, the machine is started and the shaft F revolves in the direction indicated by the arrows. The rotation of the disk N operates the plunger T4, raising it and carrying a number of slugs on its head T3, which remains horizontal till the lip t comes in contact with the guide-plate T3, when it is tilted, as shown by dotted lines in Fig. 4, andv throws the slugs down such plate to the raceway, where a number of them will settle themselves in the channel S4, and others fall down between the raceway and the side of the pot into the bottom of same again. Those slugs which enter the channel will slip down to the lower end of the raceway and be checked by the escapement-spring U, till by the rotation of the cam M the lever U6, by its end falling into the depression m, is moved to rock the lever U3 forward, and thereby causes the finger U2 to come in contact with the spring U and press it out of the Way of the slugs, while at the same time the point ot' the finger U4 inserts itself between the bodies of the irst and second slugs, and by means of its beveled end moves the former out of the raceway to be held between the edge of the mouth of the channel Q3 of the chute on one side and the edge of the retaining-spring X4 on the other. The further rotation of the cam M of course restores the two escapementiingers to their former position and then causes the opposite movement of the lever UG, by means of the rise m coming in contact with its end, which serves both to lower the pin or opener X7, so as to press the retaining-spring X4 out and release the slug, and' also to lower the knocker Y, which., if the slug fails to fall down the chute of itself, hits it and thus impels it` down. The rebound in the return of the lever U to its normal position throws the agitating-rod X in the raceway against the points of the slugs', thus loosening any that might be sticking. Falling down the channel Q3 of the chute the slug is again detained at the point Z (indicated in Fig. l1) bythe placerR,which ascendsasthedriver O descends, although this detention 'is not IIO absolutely necessary when the escapelnent device is working properly. By the time the placer has passed up into its own channel Q2, leaving the slug free to drop lower, the driver O is blocking the point of entry into its channel, and therefore the slug is arrested at such point; but as the driver ascends the placer n ears the slug and finally pushes it into position between the holder Q and the side of the channel Q. As the placer retreats the driver descends to drive the slug; but just before this occurs the horn is automatically raised to press the work firmly in place, as follows: The rise k of cam K comes in contact with and presses down the bar K2, which depresses the outer end of the clamp-plate K4, causing 1t to grip the rod K' and move same down, thus through the lever D2 raising the horn. As soon as the slug is driven the riselon cam L comes in contact with the bent end of the rod L', and in raising it the clamp-plate K5 is tilted upward, causing it to grip the rod K and move same up, thus lowering` the horn through the lever D2, easing the work and allowingl the feed mechanism to be operated by the rise lV 'of cam M through the levers P4 and P2.

What I claim is as follows:
